My band's last rhythm guitarist had a DSL 100 halfstack and I could easily keep up with his volume with my DSL 50. I noticed more of a volume difference with a speaker change (Vintage 30's to Greenbacks) than with a wattage change. The only way you could tell the difference btween our 2 through the same cab is that his clean channel sounded better at high volumes. This is mainly a headroom issue, but the DSL 50's clean still sounds great.
